Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below by way of examples with reference to the accompanying drawings.
In practical applications, whether the commodities in the orders are delivered out of the warehouse or the commodities in the orders which are returned to the warehouse, the sub-broadcasting method can be used for assisting in implementation. Wherein,
when goods of a plurality of orders are delivered out of the warehouse, a sub-broadcast list can be generated according to the orders, each goods in the sub-broadcast list is collected according to the variety, and finally the collected and collected goods are delivered to a sub-broadcast system and a cross belt to realize sub-broadcast according to the orders (namely, the goods belonging to the same order are sub-broadcast to one grid of the cross belt for packaging and delivery). According to the one-time distribution requirement of the existing distribution method, the number of orders (one order is one seed when the distribution is performed according to the order) cannot exceed the total number of the grids of the cross band, otherwise, the full-quantity distribution of commodities to the orders cannot be realized in one-round distribution.
When the commodities in the orders are returned to the warehouse, a sub-broadcasting list can be generated according to the orders, and the commodities in the sub-broadcasting list are delivered to the sub-broadcasting system and the cross belt to realize sub-broadcasting according to the storage areas (namely, the commodities belonging to the same storage area are sub-broadcasting to one grid port of the cross belt for packing and returning). According to the one-time full-volume distribution requirement of the existing distribution method, the number of storage areas to which commodities in a distribution list belong (one storage area is one seed when the distribution is carried out according to the storage area) cannot exceed the total number of grid openings of the cross band, otherwise, the full-volume distribution of the commodities to the storage areas cannot be realized in one-round distribution.
It can be seen that, since the existing unicast method only supports one unicast, the number of seeds in the unicast list is required to be not more than the total number of the cross-bands used for the unicast of the commodity of the unicast list, and if the number of the seeds exceeds the total number of the cross-bands, the unicast process cannot be carried out.
The invention provides a sub-sowing method for supporting secondary sub-sowing, which solves the problem that the sub-sowing process cannot be carried out when the number of seeds with a sub-sowing single weight exceeds the total number of grids of a cross band.
The technical scheme provided by the invention is described in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a multicast method according to a first embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step 101, obtaining a unicast list.
In the embodiment of the invention, the seed distribution list comprises at least one seed, and each seed comprises at least one commodity. The structure of the unicast sheet may be as follows: the seed 1, commodity 11, commodity 12, …, seed 2, commodity 21, commodity 22, …, … ….
And 102, calculating the number of the grids for secondary sowing according to the number of the seeds and the total grid number of the crossed strips when the number of the seeds in the sowing list is larger than the total grid number of the crossed strips for sowing the commodities in the sowing list.
In the embodiment of the invention, when the number of the seeds in the sub-sowing list is not more than the total number of the grid openings of the cross bands for sub-sowing the commodities in the sub-sowing list, the full sub-sowing from the commodities to the seeds can be realized in one round of sub-sowing, so that the method is realized according to the existing sub-sowing method.
Step 103, dividing the grid openings of the cross band into primary and secondary grid openings according to the number of the grid openings for secondary distribution.
In the embodiment of the invention, in one round of sub-sowing, at most one seed is allocated to a first sub-sowing grid port participating in sub-sowing, the commodity belonging to the seed is sub-sown to the first sub-sowing grid port, at least one seed is allocated to a second sub-sowing grid port participating in sub-sowing, and the commodity belonging to the seed allocated to the second sub-sowing grid port is totally sub-sown to the second sub-sowing grid port.
Step 104, distributing one seed in the sub-cast list for each primary sub-cast grid, and distributing the seeds not more than the number of the primary sub-cast grid in the sub-cast list for each secondary sub-cast grid.
The number of seeds distributed by each secondary seed-dividing grid port is not more than that of the primary seed-dividing grid ports, so that the total seed-dividing of commodities to seeds can be realized in one round of seed-dividing when the commodities which are distributed to the secondary seed-dividing grid ports are re-divided, and the third seed-dividing is not needed.
Step 105, according to the seeds allocated to each primary multicast grid and the seeds allocated to each secondary multicast grid, the commodities in the unicast list are multicast, and the commodities multicast to each secondary multicast grid are multicast secondarily by using the primary multicast grid.
In this step, when the commodities in the unicast list are distributed according to the seeds distributed for each primary unicast grid port and the seeds distributed for each secondary unicast grid port, all the commodities belonging to one seed distributed for each primary unicast grid port are distributed to the primary unicast grid port by the cross band, so that the commodity distribution belonging to the seed is finished, and the commodities can be packaged and delivered or put in warehouse; all the commodities belonging to the seeds allocated to each secondary division port (the seeds allocated to the secondary division port are also called secondary division seeds) are cross-banded to the secondary division port, and since the commodities belong to at least one seed (i.e., the commodities belong to the secondary division seeds), the further sub-sowing needs to be performed.
In addition, when the first-time dividing grid openings are used for carrying out secondary dividing on the commodities which are divided into each second-time dividing grid opening, the number of seeds which are allocated to each second-time dividing grid opening is not larger than that of the first-time dividing grid openings, so that when the commodities which are divided into the second-time dividing grid openings are divided again, each seed can be independently allocated to one first-time dividing grid opening, and once, the total dividing of the commodities into the seeds can be realized when the commodities are divided again, and the third dividing is not needed.
According to the embodiment of the invention shown in fig. 1, when the number of seeds in the unicast list is more than the total number of the grid openings in the cross band, the secondary unicast grid openings are reserved, the commodities of a plurality of seeds are distributed to the reserved secondary unicast grid openings, and the commodities distributed to each secondary unicast grid opening are distributed again by utilizing the primary unicast grid openings, so that the unicast process can be continuously executed, and the technical problem that the existing unicast only supports one-time unicast is solved.
Referring to fig. 2, fig. 2 is a flowchart of a multicast method according to a second embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step 201, obtaining a unicast list.
And 202, calculating the number of the grid openings for secondary sowing by adopting a formula I when the number of seeds in the sowing list is larger than the total number of grid openings of the cross bands for sowing the commodities in the sowing list.
The first formula:wherein x is the number of the grids for secondary sowing, b is the total number of the grids of the crossed bands, and c is the number of the seeds.
The first formula:in (I)>The representation is rounded down, (b+1) 2 -4c has a minimum value of 0.
In the embodiment of the invention, when the number of the seeds in the sub-sowing list is not more than the total number of the grid openings of the cross bands for sub-sowing the commodities in the sub-sowing list, the full sub-sowing from the commodities to the seeds can be realized in one round of sub-sowing, so that the method is realized according to the existing sub-sowing method. When the number of seeds in the sub-broadcasting list is larger than the total number of the grid openings of the cross bands for sub-broadcasting the commodities in the sub-broadcasting list, the number of the grid openings for secondary sub-broadcasting can be calculated by adopting the formula, the grid openings for secondary sub-broadcasting (called as secondary sub-broadcasting grid openings for short) are determined according to the number of the grid openings for secondary sub-broadcasting, and other grid openings are all used as primary sub-broadcasting grid openings.
In practical applications, other methods may be used to determine the bin for the secondary distribution, for example, a certain bin is directly determined as the bin for the secondary distribution, and all the other bins are taken as primary distribution bins, in this case, the number of seeds to which the commodities distributed to the secondary distribution bin belong may exceed the number of primary distribution bins, so when the commodities distributed to the secondary distribution bin are distributed for the secondary distribution, the total quantity of the commodities to the seeds in one round of distribution may still not be satisfied, and therefore, the third distribution and the fourth distribution … … may need to be continued until the distribution of all the commodities to the seeds is achieved.
And 203, dividing the grid openings of the cross band into primary and secondary grid openings according to the number of the grid openings for secondary distribution.
In the embodiment of the invention, in one round of sub-sowing, at most one seed is allocated to a first sub-sowing grid port participating in sub-sowing, the commodity belonging to the seed is sub-sown to the first sub-sowing grid port, at least one seed is allocated to a second sub-sowing grid port participating in sub-sowing, and the commodity belonging to the seed allocated to the second sub-sowing grid port is totally sub-sown to the second sub-sowing grid port.
In this step 203, the method for dividing the cross band into the primary multicast ports and the secondary multicast ports according to the number of ports for the secondary multicast is as follows:
and selecting the grid openings of the number of the grid openings for secondary sub-broadcasting from the grid openings of the cross band, taking the selected grid openings as secondary sub-broadcasting grid openings, and taking the rest grid openings which are not selected as primary sub-broadcasting grid openings.
Step 204, distributing one seed in the sub-cast list for each primary sub-cast grid, and distributing the seeds not more than the number of the primary sub-cast grid in the sub-cast list for each secondary sub-cast grid.
In the embodiment of the invention, in one round of sowing, the seeds distributed to different grids are different, and the situation that one seed is simultaneously distributed to a plurality of grids does not exist.
In this step 204, a specific method for distributing one seed in the unicast list for each primary unicast grid port and distributing the seed not more than the number of primary unicast grid ports in the unicast list for each secondary unicast grid port is as follows:
for each one-time multicast grid, selecting one seed which is not allocated from the multicast list to be allocated to the one-time multicast grid;
for each secondary sub-sowing lattice, if the number of seeds which are not distributed in the sub-sowing list is larger than that of the primary sub-sowing lattice, selecting the seeds which are not distributed in the sub-sowing list and have the number of the primary sub-sowing lattice to distribute to the secondary sub-sowing lattice, otherwise, distributing all the seeds which are not distributed in the sub-sowing list to the secondary sub-sowing lattice.
In the embodiment of the invention, the number of the seeds distributed by each secondary sowing lattice opening is not more than that of the primary sowing lattice openings, so that the total amount of the commodities to the seeds can be realized in a new round of sowing when the commodities which are sowed to the secondary sowing lattice openings are sowed again, and the third sowing is not needed.
Step 205, according to the seeds allocated to each primary multicast grid and the seeds allocated to each secondary multicast grid, the commodities in the unicast list are multicast, and the commodities multicast to each secondary multicast grid are multicast secondarily by using the primary multicast grid.
In the embodiment of the invention, according to the seeds distributed for each primary sowing lattice opening and the seeds distributed for each secondary sowing lattice opening, the commodity in the sowing list is sowed, and the implementation process is as follows: and scanning the commodity in the multicast list, determining the seed to which the commodity belongs, and sowing the commodity to the grid (primary sowing grid or secondary sowing grid) to which the seed to which the commodity belongs is allocated. Since each one-time sowing lattice is only allocated to one seed, only the commodity belonging to the seed can be sown to the one-time sowing lattice, and after all the commodity belonging to the seed is sown to the one-time sowing lattice, the commodity can be packed and delivered/put in storage. Since each secondary dividing grid is divided into at least one seed, all commodities belonging to the seeds are divided into the secondary dividing grid, therefore, if the secondary dividing grid is only distributed to one seed, all commodities divided into the secondary dividing grid can be directly packaged and delivered/put in storage, but if the secondary dividing grid is distributed to a plurality of seeds, the commodities divided into the secondary dividing grid are not the same seed, the secondary dividing grid needs to be divided again, and the secondary dividing of the commodities divided into the secondary dividing grid can be realized by the primary dividing grid in the previous round of dividing.
In the embodiment of the present invention, before the secondary distribution of the commodities distributed to each secondary distribution grid by using the primary distribution grid, the method may further include: judging whether the commodities which are distributed to the secondary distribution grid openings belong to the same seed, if so, determining that the commodities which are distributed to the secondary distribution grid openings are distributed, and prohibiting secondary distribution of the commodities which are distributed to the secondary distribution grid openings, otherwise, performing secondary distribution of the commodities which are distributed to each secondary distribution grid opening by using the primary distribution grid openings.
The method for carrying out secondary distribution on the commodities distributed to each secondary distribution grid opening by utilizing the primary distribution grid opening specifically comprises the following steps:
for each primary sub-sowing lattice opening, selecting one seed which is not distributed again from the seeds distributed for the secondary sub-sowing lattice opening to be distributed to the primary sub-sowing lattice opening;
and according to the seeds distributed for each primary distribution grid, distributing the commodities distributed to the secondary distribution grid again.
As can be seen from the embodiment of the present invention shown in fig. 2, in the present invention, the number of the gates for the secondary multicast is calculated by using the formula one, and the optimal number of the gates for the secondary multicast is calculated by using the formula one, so that the process of the multicast of the commodity in the multicast list can be completed in the two-round multicast without performing the multi-round multicast such as the third round multicast and the fourth round multicast … ….
In practical application, when the worker manually picks up goods according to the goods in the distribution list, the situation of missing or multiple goods may exist, so that the goods can be scanned first when the goods are picked and sent to the cross belt for distribution, whether the goods are redundant goods is determined, and the redundant goods are not placed on the cross belt for distribution but placed at a first designated position for waiting for warehouse returning treatment; in addition, after all the commodities are distributed to different grids, whether the commodities in each grid are out of stock or not can be judged, and the commodities cannot be packed and put in/out of stock continuously in the absence of stock, but are placed at a second designated position to wait for replenishment.
The following is a specific example to illustrate the multicast method provided by the present invention.
Assuming that 30 orders for withdrawal are included in the order, 50 items are included in the orders, the 50 items are divided into 18 storage areas, and in order to put the 50 items in storage, the order may be separated using a cross-belt having 10 slots.
Based on the above assumption, it can be seen that during the sub-sowing process, the storage area exists as seeds, i.e. 18 seeds, and 10 cross-belt gates. Because 18 is greater than 10, the full-size seed-to-seed distribution of the commodity cannot be completed in one round of seed distribution.
For this purpose, equation one above is used:the number of bins for the secondary distribution is calculated, b=10, c=18, so x=1 can be calculated, i.e. the number of bins for the secondary distribution is 1.
Assuming that the number of the cell openings is 1 to 10, dividing the cell openings 1 to 9 into primary sub-broadcasting cell openings according to the number 1 of the cell openings for secondary sub-broadcasting, and dividing the cell opening 10 into secondary sub-broadcasting cell openings;
assuming seed numbers 1 to 18, seeds 1 to 9 are allocated to the respective apertures 1 to 9, and seeds 10 to 18 are allocated to the aperture 10.
According to the seeds allocated to the first-time sowing lattice openings (lattice openings 1 to 9) and the seeds allocated to the second-time sowing lattice opening (lattice opening 10), the commodities in the sowing list are sown by utilizing the cross bands, finally, the commodities belonging to the seeds 1 are sown to the lattice opening 1 for packing and warehousing, the commodities belonging to the seeds 2 are sown to the lattice opening 2 for packing and warehousing, … …, the commodities belonging to the seeds 9 are sown to the lattice opening 9 for packing and warehousing, and the commodities belonging to the seeds 10 to 18 are sown to the lattice opening 10.
Since the commodity distributed to the gate 10 belongs to a plurality of seeds, the commodity distributed to the gate 10 is required to be distributed again, and thus the commodity distributed to the gate 10 is distributed again by using the gates 1 to 9. Specifically, seeds 10 to 18 may be allocated to the respective bins 1 to 19, i.e., bin 1-seed 10, bin 2-seed 11, … …, bin 9-seed 18, and then the commodities allocated to the bins 10 are re-allocated according to the seeds allocated to the bins 1 to 9, and finally, the commodities belonging to the seeds 10 are allocated to the bin 1 for packing and warehousing, the commodities belonging to the seeds 11 are allocated to the bin 2 for packing and warehousing, … …, and the commodities belonging to the seeds 18 are allocated to the bin 9 for packing and warehousing.
So far, through two rounds of sub-sowing, all commodities in the sub-sowing list are sub-sown, and packaged and put in storage (commodities of different seeds are sent back to different storage areas).
